How should F1 shake up its race format?

Formula 1 constantly grapples with an incessant drive to innovate that often risks offending the history and tradition that underpins its appeal. I guess this is why proposals to shake up the long-established format of grand prix weekends have received a mixed reception in the F1 paddock.

On the one hand, we have traditionalists, such as four-time world champion Sebastian Vettel. We know he's 'old school' and a bit of a historian; countless times he's shown his penchant for F1's record books, and his feelings about the sound made by F1's current small-capacity hybrid turbo engines are also well known. Vettel doesn't want F1 to do anything that would detract from the splendour and grandeur of Sunday's racing.
